SPECIFICATION forming part of Letters Patent No. 626,387, dated June 6,1899.

Application filed ObOr 5, 1897.

To all 1072 0772 it may concern:

Be it known that I, LINDLEY S. LAWSON, a citizen of the United States,residing at Homestead, in the county of Allegheny and State ofPennsylvania, have invented or discovered new and useful Improvements inGas-Burners, of which the following is a specification.

In the accompanying drawings, which make part of this specification,Figure l is a side elevation of myimproved gas-burner; Fig. 2, a plan ofsame; Fig. 3, a side elevation, enlarged, of one of the lid-burners; andFig. 4, a vertical section of Fig. 3.

The purpose of my invention is a compound range gas burner of equalefficiency with those ordinarily used, but much cheaper in construction,as the main portions of the burner are inexpensive castings and thebalance ordinary gas-pipe.

In the accompanying drawings, which make part of this specification, 2is a casting which constitutes the main burner in the grate of therange. This castingis provided with suitable apertures 2 2 to permit ofthe passage of the gas. Extendinglaterally from said casting andpreferably formed integrally therewith are the hollow lugs 2 2, saidlugs, however, not communicating with the hollow interior of the mainpart of the burner. 2 and 2 4, each of which is provided at its outerend with a suitable airnnixer 3 and 4E and independent gas-valve 3 and4.

The main burner 2 is tapped at one end to receive a short pipe 5, whichlikewise has a suitable air-mixer o and independent gasvalve 5.

Serial No. 654,177. (No model.)

In the upper side of hollow lugs 22 and 2 are threaded one or more shortpipe-sections 6 6, which are capped by a peculiar mushroom-shapedlid-burner '7, each mushroom burner communicating, respectively, withpipes 3 and l. This lid-burner is cast so that its top forms an invertedcone 7, projecting downward into the burner. The periphery of the burnerimmediately below its top is surmounted with slots 0r apertures 7 7 forthe passage of the gas.

8 8 8 are plugs secured in the openings used for cleaning the interiorof burners of the byproducts of combustion, &c.

My built-up burner can be constructed much more cheaply than it ispossible to cast an entire burner embodying all its features, while itis easily assembled and taken apart.

The shape of the lid-burner secures a very uniform distribution of gasaround the entire periphery of the burner.

Having described my invention, I claim- A main burner cast with hollowprojections integral therewith, said projections having no gascommunication with the main burner; independent mushroom burnersdetachably mounted upon said projections; independent gas-pipe section'sconnected with each of said projections and with the main burner.

In testimony whereof I have hereunto set my hand this 30th day ofSeptember, A. D. 1897.

LINDLEY S. LAWVSON.
